Subject: [PATCH] ffi: Add public `set_version` function

Somehow Cargo didn't complain about the previous generated ioctl function
being unused, but does now with the macro based on Rustix.

Taking an `&mut` matches the API of `drmSetInterfaceVersion` in libdrm,
so it makes sense to just stick with that.
